Puncture wounds, except gunshot wounds

An employee was repairing an abrasive blasting pressure pot. The employee turned off the blasting machine before leaving the area to get a different tool. While the employee was away, a coworker turned the machine back on. When the employee returned to continue work, the coworker triggered the system, striking the employee with pressurized blast media. The employee suffered a serious abrasion and punctures to the face, neck, torso, arms, and leg, requiring hospitalization. The machine was not locked/tagged out at the time of the incident.
